We started business as a Nishijin textile manufacturer, where Nishijin textile craft workers started up a factory to manufacture textile fabrics. Since 1992, we have been working on the development, manufacture and sale of silver-metalized fiber AGposs®. We started AGposs® with antibacterial products, and received attention that silver has high conductivity through them. AGposs® has been highly valued as conductive fibers ever since. Taking advantage of our experience as the textile manufacture, we keep striving to produce and manufacture fibers to meet customers' needs.

Management philosophy
